' f -BatentedvMayfagieietll applic-monikaAugrstae,1913. vseria'ilm'), 787,343.1 f t To allfwhom it may conce/rma l f Bei-t known that I, HERMAN G.'METZ1G, a citizen of thefUnited States, residing at Berlin, in the county of Green Lake and y 5 State of Wisconsin, have invented a new and useful Automobile 1Wheel-J ack, of lwhichthe following i's a specification. r The present invention appertains generally to vehicle jacks, and relates more par- 10, ticularly to a jack for automobiles or pneumatic-tired wheels. v Y

4It is the object of the present invention to rovide a novel and improved jack for raising y the wheels of an automobile, when the auto-mobile is idle or out ,of use, inorder that the pneumatic vtires may be relieved of the strain due to` the weight of the machine, whereby the life of the tiresmay be lengthened materially.

Another object of the present invention is toA provide a ja'ck of the nature indicated, which shall be of such peculiar construction as to best adapt it for the purposes intended, and in order to carry out. the results desired,- iny an eflicacious manner.

1t -is also within the spirit of the. invention, to provide a device of the nature specified which shall be of comparatively simple,I compact and inexpensive construction, as well as being. convenient and eflicient in its use. 1* Y Withfcthe yforegoing general objects outlined, `andwwith other .objects in view, whichy will be apparent as the .nature of `the invention is better u'nderstoodthe present inven tionvresides in thecombination and arrange-'l ment of parts and in lthe details-,oflconstruction hereinafter described and claimed, it being understood that changes inthe precisevl 40 embodiment of the invention herein dis'- closed, can be made within the scope of .what is claimed, without departing from'the spirit of the invention. l

The invention has been. illustrated `in itspreferred embodiment in the accompanying drawing, wherein f Figure 1 is an elevation of theimproved jack, as applied to an automobile wheel. Fig. 2 is a side elevation ofthe jack prior to application tothe wheel, and illustrating the parts of the jack in final. position in dotted lines. ,v f ,l Y The present device embodies Yin itsy essen-v tials two members or elements, namely, a lever-, ande-a .thrust .or lifting member.- These f elementsV areY each of a peculiar construction.v

and `are operablyfconnected such ner asto carry outthefunctions desired inca: highly eiicient manner.`

Referring speccauyto the' 60 lever is constructed from'abar or strap 1of suitable metal,which is doubledttof provide the arms l, and the baseor shoe2 connectingthe lower ends of the yarms 1 wThe-Larinsl: preferably converge toward :their upper Aor; 6,5 free lends, and their free ends are connected by a cross bar 8, on which awooden orf other suitable handle t isrotatably mountedf'be-f tween the ends of thearms 1.5? Thef'arms'l are 4connected intermediate theirlendsybyl a; 70 cross bar or stay 5the ends of the vmembers 3 and 5' being preferably riveted throu' l1 the f. arms l. Below thecross bar or mem er `5,I each arm l is provided with aseriesoff apen tures or yholes 6, which extend upwardly- 75 from the shoe or base 2. l Y, f"-"f. Thethrust orfy liftinglmemberis fashioned from. a lrod or suitable vlengthwof metallic-j stock, which is doubled to ,forme-'the' arms v7 and .the curved or arcuate yoke'8: connect?y go ing the arms at one end. Thearms- "pref-l erably diverge away from'fthefyiokeaf'and are provided at thelrlfree ehds {with theljan# gular portions 9 bent awayfrtgnrfeacht other,

which lare designed lto'sn'ap @outwardly g5 through thel respective aperturesl 6i to 'pivota the thrust member *betweenthe' leveiarms or tothe inner sides thereof.' ItJis-:evident that by engaging theangular ends 9 'of thearms 7 throughlthe various fapertures?6,'5'the-l 90 thrust 'or lifting member may beladjusted with respect tothe lever; The-arcuate yoke'` w 8` provides a hub seat, and iswpaddedby means of 'a leather or 'similar facing "210 wrapped thereover, the ends ofthe covering orv facing 10 being attachedfby means'E of rivetsv or other' securing'members 11".: The ends of the pad or covering; 1104 V'are -prefer-f ably disposed between the;l l arms 17, to expose thef'intermediate orune'ricumbercd *portion 100 ofthe pad to th'e hub`,as"will`hereinafter aptpear.. AAlatch is carried by"'th'e crossbar 5v *i of the lever, and embod'i'es'ii"wirecoil 12F loosely-embracing the cross bart5,and hav? ing one terminal formed .into2 a hook `13 to"" 105 engage one varrn?` of the thrust oriliftingf l member. y

In use, the thrustv ortliftin'gmemberiis'VA first adjusted properly with 'respect to the ,le-ver, to accommodatethe particular ldiam- .11C

eter or size-of the automobilewheelwhich isvtozbe raised, and'thefpadded'seat-is" then v The latch mounted on the' cross'bar 5 is Athrough the medium .of the hand the free end of the lever, or handle 4, '1st engaged under the'outer end the wheel hub, as suggested in Fi 2, with the base 2 -of the lever resting on t e floor or underlying surface below the hub. The free end of the lever is then swung upward by hand, le 4, unt-1l brought against thejspokes of the wheel.

then slipped or moved into engagement with the-respective arm' 7 ofthe thrust member,

the lever, in order that the handle 4 may swingagainst the upper spokes of the wheel.

It is also to be observed that the'lever and thrust member are each of U-shape, the termi- I nals of the thrust member 'being ladjustably thrust member is formed into a seat or hub- 'engageable with the arms of1 the lever, .the `intermediate portion of the lever forming a foot or base to engage the Hoor, while the .ends of the lever are connected by a handle, and while the intermediatev portion of the engaging portion.

Attention is directed to the fact that the lever is relatively long, while the thrust member is relatively short, in order that the free end of the thrust member, which is provided with the hub seat, will terminate short of the handle 4'or the terminals of the lever. Thus, when the lever is raised, as seen in Fig. 1, theterminal portions of the lever are adapted to receive the hub engaged by the hub seat, to assist in maintaining the jack in position with' respect to the hub. Thus, the hub will be disposed between the arms or terminal portions of the lever, and between the hub seat and handle.

In practice,`one ofthe improved jacks is employed in connection with each ofthe wheels ofan automobile, in lorder that the entire machine may be raised, to relieve all of the pneumatic tires ofthe weight of the machine. The construction of the device is such, that it will not injure the finish of the hubs or spokes when jacking up the wheels, or when t-he jacks 'are removed, s'o as to permit the machine to rravitate onto the floor. The said jacks maylbe readilyand effectively applied to the wheels of a vehicle, and carry out the objects aimed at in a- 'satisfactory and desirable manner.

Having thus described, the invention what is claimed as new 1s 1. In a Jack, a U-shaped lever, a thrustl member having one end pivoted between the arms of the lever, the free end of the thrust` l member being provided with a hub seat and 'the terminals'of the thrust member being pivoted to the inner sides of the arms of the lever, the intermediate portions of the lever and thrust member being formed into a foot and hub seat, respectively, and a handle connecting the terminals of the lever, the terminal portions of' the' lever being arranged to receive a hub engaged by the hub seat.
